· Water
Discussion Topic
One student looked at the relationship between photosynthesis and respiration and thought that plants could survive without animals.
How are carbon dioxide and oxygen used by plants and animals? Does this have an impact on whether plants need animals?
Are there any circumstances other than metabolism where animals may have an impact on a plant's continued survival?

· Cellular Respiration vs Respiration in the Lungs
Discussion Topic
A few students are confusing cellular respiration with respiration in the lungs which involves the exchange of gasses (oxygen and carbon dioxide) in the lungs.
Please compare the 2 processes. How are cellular respiration and respiration in the lungs different from each other? How are they related?
